“Most of us are desk sitters,” says Jubilee. “Since we now have such sedentary lifestyles, we no longer need to be fueling our bodies with high-energy fuel, which is what carbohydrates provide.”

But it’s not just about low-calorie, low-carb eats — also key are healthy fats found in plants, nuts, seeds and fish; vitamin- and mineral-packed vegetables; and lean proteins. (Meats are OK as an accent.)

Luckily, there are loads of fast, healthy options in the city that fit the bill.

Here, Jubilee makes her top recommendations for exactly what you should be ordering on your next lunch break and why.

Nicoise tuna

The seared tuna is a quality protein; the olives provide healthy fats; and the tomatoes have lycopenes, which Jubliee says boost your immune system. And eggs are one of the few foods that contain natural vitamin D. “They’ve linked low vitamin D levels to cancer and diabetes,” says Jubilee.

Even the potatoes have a healthy kick since the skin, where the good-for-you fiber exists, is still attached.

Wild sockeye salmon

At Dig Inn Seasonal Market, $12.40; 696 calories

The fish is rich in omega-3 fatty acids, which help keep you feeling full longer and boost your immune system. Brown rice is full of fiber, which is important for digestion and maintaining a healthy weight.

Avocado toast and salad

If you’re craving a sandwich, this avocado toast is good because it comes with a gluten-free bread option, but even if you stick with the organic whole-wheat sourdough, you’re still only getting one slice of it. “It’s less bready, even though you get the satisfaction of the bread,” says Jubilee. “You also get healthy fats from avocado. The chia seeds sprinkled on top add omega-3 fatty acids.”

How to stay full all day

• Stop following the old advice of eating small, frequent meals. If you’re trying to lose weight, order a substantial-enough meal at lunch and don’t bother saving half for later. “Researchers are starting to see if we eat less often, the benefits for weight loss are pretty huge,” says Jubilee. That’s because if you’re constantly munching, you never give your body a chance to tap into fat reserves, burning them in the process, she explains.

• Plagued by midday snack pangs? For those looking to lose body fat, Jubilee recommends grabbing a small, low-carb snack: a handful of nuts, a 5-grams-of-sugar Kind bar, or crudités and hummus instead of chips or a cookie. Loaded with nutrients, it doesn’t take much of these snacks to satisfy the munchies.

• It’s okay to add whole-fat milk to your tea or coffee. “Fat is not making us fat, it’s sugar that gives us heart disease,” says Jubilee. Plus, the fat from the whole milk will curb your cravings.
